YOu can validate get values, sorry I haven't updated this when I found an answer to this problem.
If you want to validate the $_GET array or any other array for that matter just do this:
Code:
function foo(){
$_POST = $_GET;
// then do your validation here
}
sometimes when I want to validate if a file was uploaded and whatnot I just do the upload and then do $_POST['file'] = $uploaded_data['file_name']; and then use form validation on that field too.
I hope this helps.
